Some asians/korean girls are really pretty but why are there eyebrows always bushy and messy?

I've been asking myself why asian girls have bushy messy eyebraus for a long long time. I dont know why they can afford to max out their credit cards to hide the bowed legs and use rogain but never spend a little to wax and fix their bushy eyebraus. That is a must because they have really black hair and cannot hide bushiness like white girls. maybe they think that cause they dont have much hair on head, they also dont have much hair below and on face. -well that just goes to show, its not always what you think.
